Constructs a NoRewindIterator.

### Parameter-Liste

### Beispiele

Beispiel #1 NoRewindIterator::__construct() example

The second loop does not output because the iterator is only used once, as it does not rewind.

`<?php
$fruit = array('apple', 'banana', 'cranberry');
$arr = new ArrayObject($fruit);
$it = new NoRewindIterator($arr->getIterator());
echo "Fruit A:\n";
foreach( $it as $item ) {
echo $item . "\n";
}
echo "Fruit B:\n";
foreach( $it as $item ) {
echo $item . "\n";
}
?>`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    Fruit A:
    apple
    banana
    cranberry
    Fruit B:
